Fire risk assessment in Westminster

The dominant form is the mansion block: red-brick or portland-stone purpose-built flats from the late Victorian and Edwardian periods, typically four to eight storeys with a single central staircase and, in many cases, a lift installed decades after original construction. Pimlico and Marylebone add stucco-fronted terraces converted into flats, often listed, where the original panelled doors and cornicing constrain what can physically be changed. Soho and Victoria have a dense concentration of hotels, licensed premises and offices interleaved with residential upper floors, so ground-floor commercial risk features heavily in assessments of the flats above. Newer development is comparatively rare and concentrated around Victoria and the fringes of Paddington.

Westminster does not currently operate a borough-wide additional or selective licensing scheme in the way that some neighbouring boroughs do, though mandatory licensing still applies to larger qualifying HMOs. Licensing designations do change, so treat this as a starting point and confirm the live position with Westminster City Council's private housing team before relying on it for a licence application.

Almost the whole borough sits inside both the Congestion Charge zone and ULEZ, and on-street parking in Mayfair, Soho and Marylebone is tightly controlled, so we typically use nearby NCP or council car parks and factor that into the visit time. Many mansion blocks are managed by long-established West End agents who hold detailed building history and previous assessments, which helps us produce a comparative report rather than starting from scratch. Access to listed buildings sometimes needs a heads-up to the porter or resident caretaker, particularly for roof-level plant rooms. Reports for straightforward mansion blocks are usually delivered within 24 hours of the visit, in line with our standard turnaround.

A significant proportion of Mayfair and Marylebone's mansion blocks sit within conservation areas or carry individual listing, which shapes how we frame recommendations rather than what we assess. Where a communal fire door needs upgrading, we set out the fire performance shortfall clearly and note where a heritage-sensitive approach — secondary glazing-style upgrades, matched joinery, or retention of original ironmongery with added intumescent protection — may satisfy both the fire safety objective and any listed building consent requirement. Porters in these buildings often hold decades of maintenance history and previous assessment reports, and we ask to review that history before the visit so recommendations build on what has already been addressed rather than repeating it.

Soho's dense concentration of hotels, licensed premises and members' clubs frequently shares a building, or at least a party wall, with residential upper floors, and Victoria has a similar mix around the station and coach terminus. Late licensing hours mean these premises are occupied and trading well past the point when residential blocks nearby have gone quiet, so alarm audibility between uses and the coordination of evacuation procedures across a shared building matters more here than almost anywhere else we work. We check whether the hotel or club's fire alarm and the residential block's system are properly independent, or whether an assumption has been made that one will alert the other without any actual interconnection.

Pimlico's grid of white stucco-fronted terraces, many converted into flats decades ago, share a distinctive pattern of communal garden squares accessed by residents, which occasionally feature as a secondary assembly point or, in a small number of buildings, as part of an escape route from a rear extension. Original panelled front doors and ironwork balconies are protected by conservation area status, so where a flat entrance door falls short of a certified fire rating we assess practical mitigation — improved self-closing devices, smoke seals fitted without altering the visible face of the door — rather than assuming wholesale replacement is the only option.

Under the Regulatory Reform (Fire Safety) Order 2005 and the Fire Safety (England) Regulations 2022, the freeholder, managing agent, landlord or employer must ensure a written fire risk assessment exists, is acted upon, and is reviewed at least annually. Buildings over 11 metres also require quarterly communal fire door checks, annual flat entrance door checks and wayfinding signage. We can deliver all of it in one visit.
